You need to think a little beyond velocity of money. Velocity of money causes inflation/deflation. Printing currency reduces interest rates which indirectly causes more borrowing which indirectly causes more spending, thus increasing velocity of money.

All of this still isn't related to the article which is talking about unequal distribution of wealth.

Sure one way to solve this unequal distribution is handing more money to poor directly by printing, but thats bound to cause inflation.
